WINDOW-FENTILATOR AND FLY-ESCAPE.

Specification of Letters Patent.

Application filed April 1'1, 1910. Serial No. 554,779.

To all whom it may concern: p

Be it known that I, GEORGE W. STEIN, a

citizen of the United States, and a resident of'Chicago, in the county of Cook and State of lllinols, have invented certain new and useful Improvements in Window-Ventilators and Fly-Escapes, of which the follow ing is a specification. v

' My invention relates to means for ventilating windows, and it consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention isto provide a window ventilator which may be brought into instant use at any time without the necessity of raising or lowering the window sash.

A further object, of my invention isto provide a device which Wlll. permit a circulation of air therethrou h, but at the same time prevent snow or ram from blowing in through the openings.

A further object of my invention is to provide a device which may be readily attached to any window, and which is simple in construction and relatively cheap to manufacture'.

Other objects and advantages of my invention will appear in the following specification and the novel features of the device will be particularly pointed out in the appended fclaims.

Myinvention is illustrated in the accompanying drawings forming part of this ap- 6 is a sectional view through the outside wall.

of'the slide casing, and, Fig. 7 is a detail view in perspective showing'a fly escape on the exterior of the outer wall of the slide casing. I

' In carrying out-my invention, I provide the ventilators of the form best shown in Fig. 5. This consists of a slide casing formed preferably of one piece and bent as shown in the figure. It will be seen that the slide casing consists of an inner side A, having circular openings a, and a longitudinal slot a provided wlth an enlarged portion a at one. end thereof. The upper edge of the side A is bent back upon itself, as shown at a.

The opposite or outer wall B of the slide casing has stamped from it 'a series of-inclined portions 6, which are curved. outwardly. The stamping out of these portions 1) provides openings 6 through which air can enter. inwardly as shown atb, while the bottom is bent back upon itself, as shown at b. The inner wall A has a small portion a bent back upon it at the bottom, and these two portions 6' and a are joined together by an integral central portion. a b.

Secured in the grooves between the top of the outer wall B and port-ion b,'and the bottom of the wall B and the portion I)! is- The top of the wall B is bent a screen G. The similar bent over portions at the top and bottom of the inner wall A constitute, with the innervwall, runwaysfor a slide D. This slide has a series of open- -.ing's d, which are arranged to register with the opening a in the inner wall A. Projecting through the slot a in the wall A is a member E, which is integral with D, or which may be secured thereto.

At certain portions along the ventilator,

I cut away the wall A, as shown at a, for

a purpose hereinafter described. The slide window sashby recessing' the, sash frame F,-

as shown at f in Fig. 4, placing the pane G between the parts 5 and a and inserting the pane and the attached ventilator in the sash frame. The operating cords H may be secured to the member E, these cords being passed through screw eyes I, which constitute guiding members.

The ventilator described. thus far is designed for use in the lower sash on the window. For the upper sash, I prefer to use the form shown in Figs. 2 and 6.

The outer wall of the upper sash is pro vided with inclined portions 6 stamped therefrom, having end I)" turned inwardly.

- the openings nor with the extension otherwise the construction is the same as that for the lower sash.

From the foregoing description of the various parts of the device, the o eration thereof may be readily understoo The apparatus may be set up as described, and if the ventilator is notto be used, the cord H at the left of Fig. 1 may be pulled thereby drawing the member, E into registration with the enlarged portion a of the slot a Now by pushing the member-E upwardly, it will engage behind the inclined shoulder e, and lockthe ventilator. When the ventilator is to be used, themember E ma be pushed downwardly and v the string of.

the opposite side may be. pulled so as to uncover the opening a to any extent desired.

The provision of the screen C prevents flies or insects from entering, while permitting air to flow therethrough. Asiswell known, a fly or other insect will follow the contour of the window, and therefore an insect walking along the upper part of the pane will enter the cut-away ortion a", pass through the opening 0 in t e screen C, and find himself on the outside of the window. He will not attempt to enter the opening again because of the sharp points 5 Where the ventilator can be reached by hand, it is, of course, not necessar to make use of the cords, for the member may be grasped and moved to cover or uncover the ventilator openings. The protecting stamped portions .5 keep the .rain and snow from entering, so that the ventilator can be left open in stormy weather without any danger from the elements.

'The ventilator described may be manufactured in all sizes to fit windows of various heights or widths. ,They may be attached to the sash of any window without the use of nails or screws. Another feature of the ventilator is that the window may be locked while the ventilator is open. Ordinarily, ventilators'of this type are placed underneath the window when it IS unlocked.

be varied at liberty, without departing from the spirit or the scope of the invention.

I claim 1. The combination with a window pane and sash, of a ventilator comprising a casing formed of a single piece of metal bent to form grooves at its bottom, and bein provided With openings, a slide within sai casing having openings adapted to register with the first named openings, and a screen arranged to cover said openings, one of the grooves of the casing being adapted to receive and hold the edge of the pane, and the opposite edge of the casing being secured to the inner edge of the sash.

2. The combination with a window pane and sash, of a ventilator comprising a casing formed of a single piece of metal bent at its top to form two grooves, and at its bottom to form three grooves, a screen disposed within said casing in one of said top grooves and in one of said bottom grooves, a slide disposed within said casing in one of said top grooves and another of said bottom grooves, said pane being held in the third bottom roove.

3. The com ination with a window pane and sash, of a ventilator comprising a casing formed of a single piece of metal bent at its top to form two grooves, and at its bottom to form three grooves, a screen disposed within said casing in one of said top grooves and in one of-said bottom grooves, a slide disposed within said casing in one of said top grooves and another of said bottom grooves, said pane being held in the third bottom groove, said slide and sald casing being provided with openings, and means secured to said slide and projecting through said casing for bringing the openings in the slide into registration with the openings in the casing for locking the slide in position.
